unist-util-visit is a utility for traversing and inspecting nodes in unist syntax trees, which are used by tools like remark (Markdown), rehype (HTML), and retext (natural language). Developers use it to walk through tree structures and apply functions to specific nodes, making it essential for building plugins and transformations that process Markdown, HTML, XML, or other text formats. It provides a simple API for visiting nodes based on type, depth, or custom filters.
